Comment 18 for bug 129307

Also note, Jelmer has mentioned that we should go ahead and probe for GET .bzr/branch-format before we use POST .bzr/smart.

We wanted to make getting to the smart server as fast as possible, but it turns out that it tends to interact poorly with foreign branch integration, etc. And I think changing the search order to GET + POST would also fix bugs like this. Servers tend to be configured very differently for POST than GET, so failures on POST are often not real failures.
